Touch panel

摘要

Disclosed herein is a capacitive touch panel having a single layer electrode structure capable of securing uniformity of capacitance distribution by decreasing capacitive coupling which may be caused by a generation of undesirable parasitic capacitance between short-range electric field lines by a sensing electrode and a ground electrode adjacent to the sensing electrode employing a mutually inclined concave and convex part toward the sensing electrode and by the sensing electrode and an adjacent driving electrode having a interdigit structure formed in the same method, in a mutual capacitive type touch panel that configures together the driving electrode and the sensing electrode on a single electrode layer having a matrix structure in which a plurality of electrodes are arranged to be intersected with each other on a base substrate.

1. A touch panel, comprising:
a base substrate; a driving electrode including a first member formed on the base substrate in one direction and second members each extended in a direction perpendicular to one direction of the first member and formed to be spaced apart from each other in one direction; a sensing electrode including a third member formed on the base substrate in a direction corresponding to the first member and a fourth member extended to an inner portion of a spaced space between the second members in one side direction perpendicular to one direction in which the third member is formed; and a ground electrode formed on the base substrate in the other side direction of the third member so as to be in parallel with the direction in which the third member is formed and having a mutually inclined concave and convex part formed at a surface thereof corresponding to the third member.
